IS200ERIOH1A
GE
Overview
The IS200ERIOH1A is an Exciter Regulator I/O from GE. It is part of GE's industrial automation product portfolio.
Application & Technical Notes
As an exciter regulator i/o, the IS200ERIOH1A is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.
Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.
Maintenance & Diagnostics
Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the IS200ERIOH1A, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications (source data)
SPECIFICATION Part Number: IS200ERIOH1A Manufacturer: General Electric Series: Mark VI Function: Ground Detector Board
Within the EX2100 system, the IS200ERIOH1A serves as an Exciter Regulator I/O board. In the EX2100 Regulator Control systems, the IS200ERIOH1A offers a system and customer I/O. (both simplex and redundant.) Depending on the type of system, the board is mounted in different locations. In simplex applications, for example, the board is mounted in ERBP. Three IS200ERIOH1A are required in redundant applications. These attach to the ERRB M2 and C, as well as the ERBP M1. The front faceplate of the IS200ERIOH1A is double wide and has various components affixed to it.
One toggle switch is included in this package. Two backplane connectors (P1/P2) are located on the board's back edge. The board includes two CPU sockets as well as a field-programmable gate array (FPGA) for data collecting and storing into DPM control. When working with simplex systems, this board also provides an interface system I/O from the ERO and ERDD boards. The board is mounted to the ERBP M1 and the ERRB M2/C in a redundant configuration. The M1/M2/C controllers are all on the same PCB. A front faceplate with many mounted components, including a toggle switch, is featured on this board. It also features two backplane connectors on the back edge, hundreds of capacitors and resistors on the surface, and several integrated circuits. Two CPU sockets and one field-programmable gate array are included in these circuits.
IS200ERIOH1A Technical Specifications Manufacturer General Electric (GE) Model Number IS200ERIOH1A Manufacturing Location Salem, VA, USA Product Type Exciter Regulator I/O Applications Redundant and Simplex About the IS200ERIOH1A Produced by General Electric for the EX2100 Excitation Regulator and the Mark VI series as a whole, the IS200ERIOH1A board offers the I/O interface for customer and system I/O. It provides these functions for Regulator Control systems both simplex and redundant. For simplex applications, the I/O is mounted in the ERBP (Exciter Regulator Backplane) and interfaces customer I/O signals for the ECTBG2 terminal board and the EPCT terminal board. The IS200ERIOH1A is also capable of interfacing system I/O signals for the EROC (Exciter Regulator Options Card) and ERDD (Exciter Regulator Interface and Dynamic Discharge). For redudant applications, it also interfaces system I/O signals for the ERRR (Exciter Regulator Redundant Relay).
The Exciter Regulator I/O is connected to the EROC and ERDD boards by means of the ERBP or ERRB backplanes, the former of which is for simplex applications and the latter of which is for redundant applications. Additionally, the ERIO is connected to the EPCT and ECTB through two twenty-five pin connectors to the ERBP and the ERRB. The FPGA (Field Programmable Gate Array) controls storage and data acquisition into DPM (Dual Port Memory). This particular unit is a revision of the original part, indicated by the "A" at the end of the model number.
